Computer Security

Computer Security is the process of prevention, detection and protection of assets of a computer or computer system. Those assets are many types involving hardware, software, data, people, processes, or combinations of those from unauthorized user, virus, worms and other related threats. Prevention measures helps to stop unauthorized users (hackers) from accessing any part of your computer system. Often they want to gain control of your computer so they can use it to launch attacks on other computer systems. It is also defined as protecting systems from cyber threats. “Cyber” is defined something “of, related to, or involving computers or computer networks.
Computer security and cyber security are interchangeably used terms, and require digital computer technology from 1946’s ENIAC to now.
Computer security and cyber security are both children of information security.
IT security is information security as it relates to information technology. IT is the application of computer science for practical purposes, largely for

  • Industry (mainframes, supercomputers, data centers, servers, PCs and mobile devices as endpoints for worker interaction) and
  • Consumers (PCs, mobile devices, IoT devices, and video game console endpoints for end-user lifestyles.)
  • IT security can probably be used interchangeably with cyber security, computer security and information security if it relates to business.
